P. L.WEIMER.= Improvement in Steam Engines.

Patented May 30,1871.

Thisi vention relates to a new and useful improvementin reciprocating steam-engines; and conslsts inthe cross he'ad, andin guides,-

tached to the bed and confine the cross-head laterally to the central line. The cross-head consists of the bed-piece or slide F and the stud G. The piston-rod rests upon the top of the stud, where it is fastened by the bolt H,

and may be adjusted vertically by means of paper or other thin material placed beneath it. The guides are confined within the flanges I I of the bed, and wear may be compensated by introducing thin strips of paper or other mate rial between the fiangesand the back of the guides. The connecting-rod from the crank of the main shaft is attached to the end of the piston-rod direct. J is the wrist for that purpose.

By this arrangement the wearing-surfaces are kept properly lubricated with perfect ease, the cross-head is kept in line, and the construction of the steam-engine greatly simplified.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. The cross-head D and guides E E, constructed, arranged, and applied together, as
